A belt-drive turntable from Sony with precision tonearm controls and a low-noise DC servo motor.
Overview
The Sony PS-2410 is a belt-drive turntable built as the successor to the PS-2400. It has a solid wood base and a removable acrylic dust cover. The tone arm is a static balanced universal S-type with several adjustments: head-shell angle, tracking, and lateral balance through an internal force cancellation system. The included IM-type cartridge has a 0.5 mil diamond stylus on a tapered cantilever, with a recommended tracking force of 1.5g to 2.5g. It was known for great sound quality and a sleek appearance, and it sat in Sony's high-fidelity turntable line.

Design
The PS-2410 uses a low-speed DC servo motor with a rubber damper to isolate vibration and reduce noise. A dedicated IC in the servo circuit handles speed switching and adjustment electronically. The turntable bearing is oil-less metal, so it needs no lubrication. The tone arm sits on a gimbal support with a high-precision pivot bearing, and it allows head-shell angle and cartridge tilt adjustments. The output cables are low-capacitance RCA types, to keep high-frequency loss down. The cabinet is thick and includes a special insulator to absorb outside vibration. A replacement shell holder is mounted on the unit.
Market
The Sony PS-2410 originally sold for ¥42,800 around 1973. A current listing in one market shows a price of ₨64,175.00. Users describe it as having great sound quality and a great appearance.
